Deviation from domestic wastewater treatment requirements 

You can apply for permission from the environmental protection authority to deviate from the basic wastewater treatment requirements in the coastal area or groundwater area. A deviation permit can be granted for a maximum period of five years at a time.

A deviation can be granted if the load on the environment is minor or the improvement of the treatment system would be financially or technically unreasonable for the owner of the property. When assessing unreasonableness, the location of the property in an area that is intended to be extended to the sewer network, the high age of the property owner and those who live permanently on the property and other similar special factors related to the life situation, as well as the property owner's long-term unemployment or illness or other similar social performance impediment are taken into account.

The granted permit expires if the use of the property changes so that the load increases or if the ownership or management of the property changes.

An application for a deviation from domestic waste water treatment requirements with attachments can be sent by e-mail to kirjaamo@hollola.fi or by post: Hollola municipality's environmental protection authority, PO Box 66, 15871 Hollola
